AUTOMOBILE ALARM SYSTEM.

Application filed February 3, 1922. 7 Serial No. 583,973. I

To all whom it may concern:

Be it known that I, HARRY C. HAY a citizen oi? the United States, residing at Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Automobile Alarm Signals, of which the following is a specification.

My invention relates to improved theft alarm signals for motor vehicles.

The objects-of my invention are the prevention of theft and unauthorized use of automobiles by a simple, audible signal that automatically operates when the slightest vibration is imparted to; the machine in any manner; to afford an alarm in a manner that will be certain to attract attention in very noisy places as on the streets oflarge cities; to provide this alarm so that it can be readily set by the rightful user without unnecessary inconvenience, and without danger of beinotampered with.

1 y invention consists in an audible signal which is adapted to be locked into operativeposition to cause an alarm when the car 0 which it is mounted is moved.

My invention also consists in the combination and arrangements of parts and inthe details of construction as herein setforth and claimed.

In the drawings:

Fig. 2 is a perspective view thereof with the cover plate removed and a portion ofthe lower part broken away;

applied to the instrument board;

Fig. 4 is a perspective view of the cover plate;

Fig. 5 is a perspective View of the flanged lock securing cap Fig. 6 is a bottom view of the bell showing the clapperheld in inoperative position;

Fig. 7 is a side elevation of a modified construction; and

Fig. 8 is a side elevation of a portion of a car partly broken away showing the modified construction in position upon the car;

In theembodiment of my invention as illustrated and which shows preferred constructions; I provide a steel bell housing 1 having sound perforations 2 in its bottom and having integrally formed thereon the lower half of the lock casing 3 which is provided with attaching flange 4i. Said bell housing is provided with steel cover plate 5,

(Fig. 4;) having sound perforations 6 there- 1n. Said cover plate is provided with slot 7 adapted to receive interlocking holding projection 8 integrally formed on the upper side of hell housing 1 and is provided with attaching flange. 9. A bell bracket 10 (Figs. 1 and 2) is secured in fixed position by set screws 11 extending into bell housing. 1. This bracket extends centrally near the top of the bell housing and has an upwardly extending spring seat and guide 12 disposed transversely of the lock casing. The bell is mounted upon the inner free end of bracket 10 which is provided with hole 13 to receive hollow machine screw 14 which passes through clapper cord bracket 15 thence through said hole 13 and into nut 16 by which the parts are firmly held together.

. A spring clapper holder 17 is secured to said and passes upwardly through hollow machine screw 14 over roller 19 and isattached to ring 23' in the end of spring support 24 attached to the rear of slidable lock 25. A coil spring 26 is mounted on said support between said lock and said spring seat and guide 12. The slidable lock 25 is mounted in the upper end of lock casingS and its inward movement is limited by set screw27. The cover plate is provided with recess 28 to receive lock bolt 29 when the device is secured in hell ringing or warning position. The shank 30 of the lock tumbler casing is cylindrical and has a longitudinal rib31 on one side which fits into slot 32 of flange cap 33 to prevent it from turning. Flange cap 33 fitsover the lock casing and against the instrument board 34 of an automobile to which the device is permanently secured by rivets35 as clearly shown Fig. 1,; thus preventing removal of the device and pre-. venting tamperin therewith. In order to stil further prevent access to the interior of the device, I provide a guard plate 36 mounted upon bosses 37 in the corners of bell housing 1, said plate being spaced apart from the walls of said bell housing to permit the sound from. the bell to pass outwardly through sound perforations 2 as indicated by the arrows. A simi- 'lar guard plate 38 is mounted upon the lower side of the cover plate upon screws 39 and spaced apart from said plate by sleeves 40 on said screws. Said plate is also spaced apart from the walls of the bell housing 1 to permit the sound from the bell to pass outwardly through sound perforations 6, as indicated by the arrows. This plate 38 like wise prevents tampering with the interior construction.

The bell clapper holder 17 is of spring construction in order that the bell clapper may be drawn securely into non-noise making position when the machine is in ordinary use and it is not desired to sound the alarm. When the lock is pushed in to release the bell clapper there are no projecting parts which can readily be tampered with to per- Init access to the interior.

My attachment is adapted to be applied to all types of cars but in some instances slight modifications in the construction of the attaching flanges are necessary in order to adapt them to the varying shapes or positions of the instrument board. This is illustrated by the modified construction shown in Figs. 7 and 8, in which the instrument board is disposed at an angle to the vertical position shown in Fig. 1.

It will be observed that this attachment is entirely independent of the steering post or other operative mechanism of the car and that when the device is locked in sound operating position an alarm will be sounded on the slightest movement of the car whether it is attempted to convey it by its own power or whether it is towed away or mounted upon a truck or other conveyance. any slight vibration either of the car itself or of the conveyance upon which it is mounted. being suflicient to operate the clapper and thus sound the alarm.

It will also be noted that the bell is enclosed in a steel casing preventing access to the interior by all ordinary means and thus insuring the safety of the car from theft or other unauthorized use.

The operation of the device is very simple. When the car is in ordinary use the lock will be in the position shown in Fig. 1 in which the bell clapper is held in inoperative position. When it is desired to secure the alarm in operative position, the operator will simply push the lock inwardly against set screw "27 when the lock bolt 29 will automatically engage recess 28 in the position shown by dotted lines and thus securely lock the devicein alarm sounding position. lVhen it is desired to again secure the device in non-alarm sounding position, insert the key into the lock and release bolt 29 whereupon the lock will again automatically slide into the position shown in Fig. 1.

Thus it is seen that the device is very convenient as it can be instantly locked by merely pushing the lock inwardly as indicated by the dotted lines, and can be quickly unlocked by merely inserting and turning the key, spring 26 automatically returning the lock 25 to non-alarm sounding position.
